SENSORED 1406-2280KV FOUR-POLE BRUSHLESS MOTOR

Product #: 060-0069-00

You asked. We listened.

For more than a decade Castle has been providing award winning brushless sensorless motors to R/C enthusiasts worldwide. In response
to overwhelming requests by our customers, we have brought technological
advancements together that will deliver unprecedented performance in
our new SENSORED motor Line. Our latest additions are the 1406 series in a "SLATE" color, in 1900KV, 2280KV, 2850KV and 3800KV. These motors are ROCK READY and we have the startup on low RPMs under control. Castle now has you covered if you are looking for ultimate control out on the trails or on your Ultra 4 track days.

WHY SENSORED?

Drivers in all applications demand clean starts when coming off the
line. Crawler fans require high-precision low speed control and torque
for climbing, racers need precision and predictability, and dragsters
don’t have a millisecond to spare. To achieve all of these performance
demands and more, we have integrated rotor position sensor technology
with our improved high power and high efficiency motor design. Through
the use of our sensors, the position of the rotor is always known by the
ESC. This eliminates the possibility of encountering cogging or
inconsistency during startup. Users will experience PRECISE throttle control and BUTTERY SMOOTH starts plus the RAW POWER and LONGER RUN TIMES that our highly efficient motors produce.

WHAT MAKES AN EXCEPTIONAL MOTOR?

When tasked with designing a sensored motor our engineers started with the question,

“What makes a motor great?”

Efficiency

You can push it harder (gear it up)

You can run it longer (with the same battery)

It stays cool under extreme loads

Reliability

Ability to withstand the harsh demands of any RC application

Long-life, high-quality components

Proven manufacturing techniques

EFFICIENCY IS KEY

The higher the efficiency of a motor the more power it can produce
without overheating, which allows you to safely run higher gear ratios.
The higher the efficiency of a motor, the less power it takes to produce
the same output power, which allows you to run longer on a single
charge. The higher the efficiency of the motor, the less energy it turns
into heat; keeping it cool under extreme loads. Efficiency equals
performance.

RELIABILITY CAN’T BE IGNORED

Without a robust and reliable design, efficiency will only go so far.
RC enthusiasts love pushing their equipment to the edge. The Castle
engineers know this and spared no expense when developing a design that
could hold up to the harsh conditions that the RC community will throw
at it. Oversized NMB bearings and vibration dampening system ensure the
longest bearing life possible. High-strength, high-temperature grade
neodymium sintered magnets combined with a high-strength Kevlar wrap
ensures the integrity of the rotor is not compromised during harsh
running conditions. Our proprietary winding techniques allow us to
produce a stator assembly that is the lowest possible resistance,
resulting in a cooler running motor. A cooler motor has a longer
lifetime. Construction of our motor required careful component
selection; each verified through internal testing to ensure the highest efficiency
possible. In the end, the result is a motor with unmatched quality,
performance, and reliability. We wouldn’t put our name on anything less.

THE DESIGN: KEEPING IT COOL

QUIETSENSE™ technology shields the sensors from magnetic
field noise generated from the motor coils and keeps your motor and ESC
in sync at all times. Use of a Flux Shield™ in conjunction with
secondary Sense Magnets delivers even HIGHER PRECISION and MORE EFFICIENT startups.

Pictured above is the Castle 1406 sensored motor magnetic flux
simulation. Simulations are an important part of the design process
ensuring optimal magnetic design.

Immense care is taken by our US design team during every step of the
development process. While using the highest quality components is
important, design is equally important. Our experienced, in-house
engineering team, located in Olathe, Kansas, has spent countless hours
simulating and developing the most efficient design. Development
includes magnetic simulations, custom winding techniques, and rigorous,
real-world testing of the final product.

During a 5-minute constant power dyno test the results were clear.
When producing 200W of power, our competitors’ motors increased in
temperature over 20% more than the Castle 1406 Sensored motor. When
producing 300W of power, it wasn’t even close, their temperature climbed
at over twice the rate of the Castle motor and then overheated in
around two minutes while the Castle motor powered through and completed
the test. _Click here for graph_

* Competitors’ motors is average of several 7.5T 2-pole motors typically used in mod-style racing.

You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder.

We take OVERPOWERING seriously.

INTEGRATED SOPHISTICATION

Castle engineers always add a little something extra in their designs
that takes your performance to the next level. We have not skimped
here. Many customers have utilized our industry leading software
functionality that Castle Link* offers. When paired with a Castle Creations sensor supported ESC, like the MAMBA MICRO X, MAMBA MAX PRO, MAMBA X or MAMBA MONSTER X, you can unlock advanced tuning capabilities that Castle Link provides specifically for sensored motors.

SMARTSENSE™ uses the motors sensors to start the motor to
provide smooth starts, excellent torque, and low-speed drivability.
Once the motor is turning, it seamlessly transitions to Castle’s ULTRA- EFFICIENT
sensorless mode. When running, a motor must transition between
different load points and a different timing advance is required for
optimal efficiency at all load points. Using mechanical timing
adjustments alone, you can only target one driving condition, such as
higher start power or higher top end speed. This sacrifices performance
and efficiency during the other driving phases. Electronic timing in SMARTSENSE™
will advance timing automatically for peak performance during all
driving conditions. This allows users to combine the best of both worlds
in an unrivaled HYBRID between smooth sensored startups and high-efficiency sensorless drive.

With a Castle sensored ESC and sensored motor you will have the ULTIMATE POWER PLANT for your vehicle. Users will experience PRECISE throttle control, BUTTERY SMOOTH starts, PEAK PERFORMANCE and EFFICIENCY throughout the full throttle range. You will feel the POWER and LONGER RUN TIMES that a WORLD-CLASS motor produces.

Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments.
